[Amagappa Shoujogun] A Firefly's Glow (Koyubi de Kakimazete)

A bespectacled teacher stands at the edge of a classroom, clutching a book as three blindfolded, pig-tailed girls in sailor uniforms await him on a bed, their small bare bodies and developing breasts fully exposed. One girl, her glasses slightly askew, addresses him as "President" and declares "This is the absolute limit of my patience" before lunging at him. He finds himself pinned beneath a slender, eager student who wraps her legs around him, whispering that she loves how his "child pussy slowly wraps around the head of my dick" and urging him to "come in." Her innocence, punctuated by breathless exclamations that "It would be the delight of any teacher," gives way to unrestrained climax as her small body trembles and she screams, "My insides are screaming." Afterward, she calls for a "very important part of the learning process" and asks to be "understood," as the other restrained girls look on with flushed cheeks.
